H n n At the forward end of the framemember '1, a platforni lfi is provided on the upper enate of 1a nt l ,d n e ri i i e i np i" same 16 that is formed integrally'with the side-frame members Sand fi'infs uch m nne'r that it con-Q l the 'vehicleand gra'l crossmem ber that si iwss be e r esdvbe m P93 9 1? m un n s le ib 'd i meme-s were 9 pa -set e t ma g ns sf we aise mb rs thats t v i as 31 ens iwtss e ui t k when new d 8 he ing of this equipment, the forward portion of the equipment deck 21 is designed to provide a crank case or oil sump 22 for receiving the engine.

The oil sump 22 is formed by providing a rectangular depression between the side-frame mem- I bers 5 and 6 and the transverse diaphragms 7 t t.

and 8' that is closed at the bottom by a diaphragm or partition 23which is provided with downward- 1y extending cooling fins 24 The rear portion of the equipment deck 21 con- W stitutes a base for receiving an electric genera' tor and is formed by providing a substantially semicylindrical depression or compartment 25 be tween the side-frame members 5 and 6 and the transverse diaphragms 8 and 9, in such manner that the generator maybe mounted in proper alignment with the engine which may be mounted in the sump portion 22. v

In order that the engine sump 22 may be adequately cooled, the cooling fins 24 extending from,

the diaphragm 23 that constitutes the bottom of 55 the sump 22, project into an air duct 30 that is disposed longitudinally of the frame member 1 i betweenthe side-frame members 5 and 6. The

air duct 30 extends forward through the bumper mrnetri'cally sisp seqw til respect 9 n To provide means for receiving the usual drawbar mechanism, a pocket 34 is provided in the bumper frame member 16 below the bumper 17. As a further economy in space, the hollow interiors of the side-frame members 5 and 6 may be utilized for the storage of oil and water or other material by, providing closure plates 35 and 3.6;,

that constitute the bottoms of tanks 37 and 38, as shown in Figs. 3 and 4.

From the foregoing explanation, it will be readily apparent that my invention provides a simple and rugged frame member and under-bed portion for a self-propelled railway vehicle.

Although I have described a specific embodiment of the. invention, it will be obvious to those skilled in the'art that modifications may be made in the details of construction'and in the proportions of the various members "of the frame structure without departing from the spirit and scope of ,the' invention, as defined in the appended claims. v

I claim as my invention: p

1. An under-bed for a Diesel-electric generating set'that comprises an integral casting for supporting an engine and a generator, said casting being providedwith apair of tanks for fuel and water that constitute the sides of asump for the engine and a compartment for the generator.

2. A railway vehicle comprising a truck structure having a center-pin connection; anintegral frame portion and power-unit under-bed mounted on the center-pin connection, said integral frame portion comprising body-bolster members for supporting a car body; an engine sump formed inthe upper surface thereof, a generator compartment in alignment with the engine sump,

tank portion formed on the sides of the engine" sump, a platform extending forward from the engine sump and a bumper portion formed across the 'end of the platform.

3. An under-bed for the power unit of a railway vehicle comprising an integral casting having a centerpin connection disposed to engage a supporting-truck structure, said integral casting comprising an engine sump disposed longitudinally thereof, a generator compartment disposed in alignment with the engine sump, a cooling air duct beneath the engine sump, tanks on the respective sides of the engine sump and generator compartment, body bolster, members extending transversely from the tank portion, a platform in front of the engine sump and a bumper portion that constitutes the forward edge of the platform. 4. An integral railway-vehicle-frame structure,

comprising a pair of box side portions that con- 'stit'ute tanks, an'engine sump disposed between the side portions, the ends of the side portions being formed to providea substantial cylindrical depression for receiving a generator, said depression being in alignment with the engine sump,

' a platform portion formed in front of the engine sump, means for mounting the frame structure on a wheeled'truck and means for mounting a car body on the frame structure.

5 A frame for railway vehicles comprising a pair of side portions'of box shape in cross'section, an integral end portion for connecting the side portions, said end portion constituting a platform,

'a bumper portion formed integrally with the end portion, an engine sump disposed between the side portions and having its bottom portion substantially level with the top of the platform portion, said platform portion and bumper being provided with a passageway for directing a stream of air against the bottom of the engine 10 sump.

6. In a frame for railway vehicles, in combination, a platform portion, a bumper portion formed integrally with the platform'portion, an engine sump also formed integrally with the platform portion, a generator-supporting portion having a cylindrically" shaped depression for receiving a generator in alignment with the engine sump and a pair of tank portions disposed parallel thereto and constituting the sides of the engine sump and generator" supporting portion.
